[Kernel-packages] [Bug 1371425] Re: linux-firmware 1.127.5, 1.127.6 causes instable network connection (likely due to iwlwifi-7260-8.ucode)
I just tried firmware 1.127 and it has the same problem as 1.127.7 Absolutly same ping spikes as https://communities.intel.com/thread/53294 on Windows OS. Solution for windows OS is in this thread. I have only ping spikes (every 1-2 minutes) nothing else. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1371425 Title: linux-firmware 1.127.5, 1.127.6 causes instable network connection (likely due to iwlwifi-7260-8.ucode) Status in “linux-firmware” package in Ubuntu: Confirmed Bug description: 1) Linux Mint 17 Qiana (MATE, x86_64) 2) Having linux-firmware 1.127.5 or 1.127.6 installed on my Sony Vaio Pro 13 ( SVP1322V8EBI product name ) 3) It causes loosy network, ping to wireless access point is unstable, it jumps from 1.8ms up to 250 and even more than 2000ms from time to time (every 3-5 minutes), repeatedly dropping packets too (no matter pinging directly a router or an external site), consistently high packet loss (about 33%), impossible to work over ssh as it takes about 10-15 seconds to type a command almost every 3rd or 5th minute, repeatedly disconnects from access point due to a limited range. 4) Normal and stable network connection over WiFi -- without lags, packet loss, disruptions, limited range, etc ... 5) Always with linux-firmware 1.127.5 or 1.127.6 --- Notes --- And there is absoultely no problem when I downgraded to linux-firmware=1.127.4 , wireless connection perfectly works, no lags, no disruptions, no packet loss, just works as expected.
